摘要

PROBLEM TO BE SOLVED: To provide a heat-sensitive recording material such as heat-sensitive recording paper which has a color development reinforcing effect of a printing part, while possessing heat and humidity resistance of a printing part, and besides, an improved heat resistance of a non-printing part.;SOLUTION: This heat-sensitive recording material contains a tris (2-methyl-4-hydroxy-5-t-butyl phenyl) butene, including water and/or methanol, as a keeping quality modifier. The above butene has a crystal structure showing a maximum diffraction X-ray peak at a diffraction angle 2θ=6.58° by diffraction X-ray measurement using X rays with a wavelength of Cu-Kα.;COPYRIGHT: (C)2009,JPO&INPIT
